U.S., Russian satellites collide
For the first time, two intact communications satellites have collided in space above the Earth, NASA officials say.
The space crash nearly 500 miles above ground created hundreds of pieces of debris Tuesday. The National Aeronautics and Space Administration said its initial evaluation is the space garbage poses a
very small though
elevated risk to the International Space Station, which orbits about 220 miles above Earth, The Washington Post reported Thursday.
Pieces of spacecraft and other materials have collided in space before but not entire satellites, the newspaper said. The debris from the two satellites will spread over time, potentially forcing NASA to have the space station take evasive action at some point, something it has had to do several times in the past.
A NASA memo called the situation
fluid, but that officials
have determined that the risk to the space station is elevated, and they estimate the risk to be very small and within acceptable limits.
